DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows the hardware architecture of a game system according to a preferred embodiment. Referring to FIG. 1, the game system includes a game input device 10, a game console 20, and a display 30.

The game input device 10 includes at least one physical object 11 and a position detector 12. The physical object 11 has an identification tag 110 therein, and identification information of the physical object 11 is recorded in the identification tag 110 such that the physical object 11 is corresponding to one virtual role in the game. The position detector 12 has a communication interface 14, and can detect position information of the physical object 11 on the position detector 12 and read the identification information of the physical object 11.

The game console 20 stores and runs game software 21. The game console 20 has a communication interface 201, which is capable of communicating with the communication interface 14 of the position detector 12 to obtain the position information and the identification information of the physical object 11. The game software 21 can change a configuration of a corresponding virtual role in the game environment according to the position information and the identification information of the physical object 11.

A display 30 communicates with the game console 20 to display a game picture.

The physical object 11 is corresponding to a unique virtual role in the game. The physical object 11 may be, for example, a chessman, a doll, a plush toy, or the like. The identification tag 110 of the physical object 11 is used to record data related to the physical object 11. The identification tag 110 may be implemented in different manners, for example, as a resistor having a specific resistance value, an integrated circuit (IC) chip, or a radio frequency identification (RFID) tag.

The position detector 12 can be used for placing the physical object 11. The position detector 12 can detect the position information of the physical object 11 on the position detector 12, read the identification information in the identification tag 110, and transmit in real-time the position information and the identification information to the game software 21 in the game console 20 via the communication interface 14. The position detector 12 is the main difference of the present invention from a conventional game system.

FIG. 2 discloses a position detector 12 according to a preferred embodiment. The position detector 12 is provided with a plurality of slots 130 arranged in an array on a surface thereof, and uses one digital processing unit 131 and a matrix detection circuit (n, m) formed by two multiplexers 132 and 133. A slot 130 with position coordinates of (Xn, Ym) is disposed at each intersection point of the matrix detection circuit (n, m). Persons skilled in the art should understand that, when the digital processing unit 131 sequentially connects the circuit of each slot 130 by scanning through the two multiplexers 132 and 133, if a physical object 11 that uses a resistor as the identification tag 110 is inserted into one of the slots 130, the resistor is electrically conducted during the scanning. A voltage value is obtained by using a bleeder circuit on the matrix detection circuit. The voltage value is then transmitted to the digital processing unit 131 so as to obtain a resistance value of the identification tag 110 on the slot 130 as the identification information (for example, 1 Ω indicates a watermelon). Then, the resistance value is transmitted to the game software 21 in the game console 20 via the communication interface 14. The game software 21 will look up a preset role database to find a virtual role ID in the game corresponding to this identification tag 110 according to an “identification information-role ID comparison table” (see Table 2 below) predefined in the role database. In another aspect, the position information of the physical object 11 having the identification tag 110 on the position detector 12 can also be obtained according to the sequence of scanning the matrix detection circuit (n, m).

The circuit architecture of a position detector 12 according to another preferred embodiment is basically the same as the above embodiment in FIG. 2, while in this embodiment, the identification tag 110 in the physical object 11 is an IC chip having a memory function. When the physical object 11 having the IC chip is inserted into a slot 130, the digital processing unit 131 can also obtain the identification information stored in the IC chip and the position information of the physical object 11 on the position detector 12.

FIG. 3 discloses a position detector 12 according to another preferred embodiment. The position detector 12 has a digital processing unit 131, two RFID readers 134 and 135, and a reader antennas 136 formed by two RFID multiplexers 132 and 133. The identification tag 110 in the physical object 11 is an RFID tag. When the physical object 110 having the RFID tag is disposed on the position detector 12, the digital processing unit 131 can also obtain the identification information stored in the RFID tag and the position information of the physical object 110 on the position detector 12.

In a preferred embodiment, a role database is stored in the position detector 12, and an “identification information-role ID comparison table” is recorded in the role database. Here, the identification information may be the resistance value of the resistor, the identification information in the IC chip, or the identification information stored in the RFID tag as described above. Once the position detector 12 obtains the identification information of the physical object 11, a role ID of a corresponding virtual role in the game can be immediately found in the position detector 12, and this role ID and the position information of the physical object 11 on the position detector 12 are transmitted to the game software 21.

In a preferred embodiment, the identification tag 110 in the physical object 11 is an element having a memory function and capable of performing a read/write operation on the identification information stored in the identification tag 110, such as an IC chip, or an RFID tag. Meanwhile, configuration information of the virtual role corresponding to this physical object 11 in the game may also be written into the identification tag 110 capable of performing the read/write operation during the game. A game player may insert this physical object 11 into a position detector 12 of another player for interacting and communicating with the other player about the game content. Besides this, achievements made by the virtual role in the game may also be written into the identification tag 110 of this physical object 11 so as to use the achievements to exchange for game awards via a physical channel or to make other relevant commercial activities.

The functions of the game software 21 disclosed in the present invention may also include a sound processing program. The sound processing program can play preset sounds via a sound output device (for example, a loudspeaker or sound output interface) according to the progress of the game, so that the game players can enjoy the sound effect and relevant sounds of the game.

FIG. 4 is a block diagram of functions of the game software 21 according to the present invention, which illustrates content of the game software and the operation relationship between the functions of the game software. Referring to FIG. 4, the game software 21 includes an environment database, a role database, a role data table, a physical object control program, a role control program, an event processing program, an event trigger program, and an image processing program.

The environment database stores environment data such as a game scene and object data in a game environment during the game.

The role database includes image data and a role ID of the virtual role and an “identification information-role ID comparison table”.

The role data table records the role ID that has appeared in the game and configuration data of the virtual role.

The physical object control program works with the position detector 12 to determine whether the physical object 11 appears, disappears, or moves, and generates real-time information of the physical object 11 at the same time.

The role control program updates a configuration of the corresponding virtual role in the role data table according to the real-time information of the physical object 11.

The event processing program at least includes a role growth processing program, a role influence processing program, a role behavior processing program, and event parameters. The configuration of the corresponding virtual role in the role data table is updated by the processing programs according to processing results of events.

The event trigger program triggers the corresponding event processing program according to the real-time information of the physical object 11.

The image processing program displays a game picture and an image of the virtual role on the display 30 according to the configuration data and the environment data of the virtual role in the game.

A representative example is provided and illustrated as follows.

The environment database stores environment data of a watermelon field, as shown in Table 1 below.

TABLE 1 Display Relative Position Object Image Position Coordinates (x, y) on ID Object Name No. (X, Y) the Position Detector F001 Watermelon Img001 X1, Y1 No field P001 Planting point Img002 X2, Y2 x2, y2 P002 Planting point Img002 X3, Y3 x3, y3 P003 Planting point Img003 X4, Y4 x4, y4 H001 Farmhouse Img004 X5, Y5 x5, y5 . . . . . . . . . . . . . . .

Therefore, once the game is started, the game software 21 will find required object data from Table 1 according to the game environment setting, and then obtain images and display positions of the objects, so as to create the game environment and display content thereof on the display 30.

The role database respectively stores the content of Table 2 “identification information-role ID comparison table”, and at least image data related to virtual roles as shown in Table 3.

TABLE 3 Role ID Role Name Role Image No. W001 Watermelon Wimg001 W002 Hami melon Wimg002 W003 Pumpkin Wimg003 . . . . . . . . .

A possible embodiment is illustrated as follows. When a game player inserts a physical object 11 representing a watermelon into a position with position coordinates of (x2, y2) in the position detector 12 and the identification tag 110 of the physical object 11 has a resistance value of 1 Ω, the game software 21 will display an image Wimg001 of the watermelon at a planting point with position coordinates of (X2, Y2) in the game environment based on the data of Table 1 and Table 2.

It can be seen from the above example that, currently, the game player has planted a watermelon (Role ID: W001) at a planting point (Object ID: P001; Display Position: X2, Y2) of the watermelon field in the game environment. That is, there is a watermelon in the current game environment. Therefore, the data recorded into the role data table is as shown in Table 4 below.
